ELECTRICAL HEATER FOR CARBURETEBS.

Specication of Letters Patent.

Application filed July 26, 1918. Serial No. 246,820.

To all lwhom. t may concern.'

Be it known' that I, WILBER A. CARTER, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Electrical Heaters for Carbureters, of which the following is a specification, reference being had therein to the accompanying drawings. lThis invention relates to electrical heaters for carbureters.

its object is to provide means for heating a carbureter by the generation of eddy currents electrically induced in an iron core surroundin" the carbureter, thus achieving an economy of current as compared to -a heater, the temperature of which is dependcnt`upon the resistance of the conductor.

A further object is to provide an electrical heater for carbureters that is particularly adapted for use when the car is standing still, as for example when in its garage.

ln the accompanying drawings: Figure l is a top view of a carbureter equipped with the hereindescribed heater;

Fig. 2 is a'view of the same in side elevation:

Fig. 3 is a vertical sectional view taken on line 3 3 of Fig'. 1.

4ln these views the reference character A designates a carbureter, the construction of which is no feature of the present invention, and B, C and D respectivelv designate an air inlet, the liquid fuelsup'oly nipe and an outlet connection for the gaseous mixture.

The heater for said carbureter comprises an iron core la' which has a cylindrical portionsurrounding the carbureter and a bottom portion extendin reter. Preferably a sight clearance or air space is left between said core and the carbureter so that the two mayr be readily assembled and disassembled. Said core is supported in the described relation ofthe carbureter by a bracket comprising la portion Fclampedl between the mixture outlet and the pipe D leading to the manifold and arms G proJectng from said portion F at beneath the carbuformed of asbestos or some asbestos product.

The upper edge of the core E is formed with slots, indicated at L, respectively accommodating the pipes B, C and D.

4In the operation of the above described heater, an alternating current being passed through the coil H results in the generation of eddy currents in the core E to heat said core. This heat is prevented from freely escaping to the .air by the heat insulation K and therefore is largely transmitted to the carbureter by radiation, convection and conduction.

In cold weather it is preferred to maintain a constant small flow of current through the coil H when the motor vehicle carrying the carbureter is standing for any length of time, 'thus maintaining in the carbureter such a temperature that no diiliculty will be experienced in starting the motor at any time.

What l claim as my invention is l. The combination with a'carbureter, of a heater therefor comprising a magnetic heating element surrounding the carbureter, a coil inductively wound upon said element, and a bracket supporting said heater comprising a portion engaged with the mixture outlet, and arms laterally projecting from said portion and secured to said element.

2. The combination with a carbureter, of a heater comprising a magnetic heating ele-- ment having a cylindrical wall surrounding the carbureter and a bottom portion extend ing beneath the carbureter and preventing access of air to the carbureter from beneath the same, and a coil inductively wound upon said magnetic element.

In testimony whereof I aix my signature. I

WILBER A. CARTER.
